OpenCV4Android ndk-build error
Hi,
I am trying to build the examples of the OpenCV SDK for Android.
I could make work the "only Java" examples but I cannot build the examples with native code.
I am under Win7, if I execute ndk-build.cmd in a command window from any of the sample project paths, I get an error like this:
/usr/bin/sh: -c line 2: syntax error: unexpected end of file
make: *** [obj/local/armeabi-v7a/objs/native_sample/jni_part.o] Error 1
I guess I have some configuration error (maybe some environment variable) but I have no experience with NDK and don't know where to look, can anybody point out where to start?
I've seen that it is recommend to use a command window with ndk-build.cmd instead of cygwin, but in case it can help, if I execute ndk-build in a cigwin terminal i get:
